control output per phase

[bkbartk]

Is it possible to control the output power per phase?

I have a 3 phase converter,
and if I turn on my dryer, I might use 3kW on phase 3 and only 100W on phases 1 and 2.
If at the same time I produce 3kW of energy, this is equally devided between the phases.
meaning I return 900W on phase 1 and 2.
and at the same time acquire 2kW on phase 3.

While I actually want all power to be distributed to phase 3 so i can use this myself. so I can save money.

Is this in anyway possible?
